Capture a full-page screenshot. Free 5 times a day per client address when the request carries no credential or key; then 0.02 USD per call. A page whose full layout exceeds 25,000,000 pixels (about 17,361 px tall at 1440 px wide) is captured from the top down to the part that fits.

Capture rules applied to both sides.

What this call was charged. The amount is a decimal USD string ("0.10"); by contrast, the x-payment-info.amount advertised on each paid operation is USD cents as an integer string ("10"). A call settled from a prepaid balance carries rail "prepaid" and the remaining balance. A call paid with a Pro account’s key carries rail "subscription", the captured pages drawn from the included allowance (2 per live pair) and the pages left; its amount is what any leftover balance and overage paid, "0.00" when the allowance covered the call.
